after spending the whole night in the water可不可以改成...after ha

可以having done是指现在分,词的完成形式作状语,表示这动作在谓语所表示的动作之前发生,通常情况是如您所言。Having driven all day,we were rather tired。(having driven表示的"先时性的行为") 常见的例外是从属关联词 after 引导的从句是带现在分词的省略句; 这个时侯,after 后面跟having done 或跟doing的意思基本上一样,如:1) After picking up his things,he hurried to the station。2)After having finished his task,he went to bed。为什么可以交替使用呢?原因是 after的词义意思是"在。以后" 替换用后,不会引起动作或存在状态在时间上与谓语的混淆。1) 和2)句的细微区别是 After + having done 更具强调性
